Man that sounds great! This is the best demo of this amp I’ve seen so far! Someone finally showcased the sweet low to medium gain sounds. Great job John!!😊
Amps like this have a very underrated clean tone. I built an 18 watt TMB Marshall from a kit about 19 years ago and loved it. Unfortunately I had to sell it. It was glorious.
Actually settled on the KT66 power tubes . They used 5881s for awhile but settled on the KT66 eventually . They also often used alternate tubes for Export market Marshalls . In the late 60s they often used something other than El34 becaaue El34s were blowing alot more in America due to differment voltages so they often used more robust tubes for American bound Marshalls like 6505s or Kt66.
I got the Marshall SC20, and I've been looking for an amp to use in a stereo setup. I felt the the SV (Super Lead) wasn't really the tone I was looking for. But here it seems as Marshall has made my new dreamamp. Not as much gain on tap as the SV or SC, but with a clean and medium gain tone to die for. As always has John shown us just how good an amp CAN sound. So I guess it's time to head to the local store to test it out for myself...
Great demo John! Nice to hear you playing. :) This sounds like the ‘60’s Plexi’s, nice and warm! I sure miss my ‘68 and ‘69 Plexi’s that got stolen from my practice space in Ottawa, ON in ‘92. I hope who ever got them put them to good use. :’( ❤ from 🇨🇦 eh! \m/, ,\m/
That’s the nature of internet “reviews.” Especially, if Sweetwater is even remotely mentioned. Robin Baker, Rhett Schule teaches you a little bit but mostly it’s sales hype.
John, PLEASE play along with backing tracks, all we hear are little scratches, that was a very cool tune!!😳 originals, no copyright issue, surf meets bluegrass? 😅 awesome, give us more!
John, what do you mean when you said at the 4:00 minute mark,? "the differance between the Marshall and the Fender Bassman is, on the marshall the 12ax7 comes first"
Hi John. I just got a Marshall JTM Studio Combo based upon your recommendation. The amp sounds great, but anytime I play a C chord (or any C note on the fretboard) I get a weird harmonic vibration. It's more pronounced with humbuckers, but still happens with my Tele. Did you get any kind of vibration from the combo you reviewed? Thanks!
There is a video explaining why but I can't remember where I ran across it. Something about the 10 sounding as good as the 12 and being able to keep the size of the amp down.
The original Creambacks were just Greekbacks with cream magnet covers then you had Grey backs and black backs but they are all the same speaker model .you had G12M 25s and G12H30s. With different color magnet caps throughout the 70s . So there was no vintage Creamack model . Vintage Greenbacks and Creambacks were the same speaker.
great demo dude if got a 76 twin reverb fender and a 50s fender and several les pauls including my 76 standard tobacco burst and cherry burst 81 custom and 89 ebony standard
the sv is the 1959 super lead's modern 20 watt version. this is(st 20) the jtm 45 2245 modern 20 watt version. the jtm is cleaner and darker the super lead is punchier and brighter.
Vintage Creambacks were just Greenbacks wirh a Cream magnet cap just like greybacks and blackbacks they were all G12M 25s or G12H30s regardless pf the magnet cap cover . Sone had 55hz cornes or bass cone and some had 75Hz or lead cone . But the vintage Creamback is not its own seperate model . I
the "low" position on the standby switch is 5w the "high" is 20w. just got mine (combo version) today, hooked it to an external cab(1974cx) with a greenback and swapped all the preamp tubes to early 60's mullards, great little amp.
2:36:"but definitely its own thing" well, if that's what call swapping power tubes from 6L6 to 5881, then ok ;) At 3:56 you mention that. You have my respect!
Outside of the classic vibe series I don't know that the price of any gear right now can be justified. Just give it time and they will get ridiculous too. Fender is only gonna listen to people talk about how great they are for the money before they jack up the price. Ala epiphone.
Just went on sale for $1200 which is a little better to stomach. I’m watching the videos because I couldn’t justify $2k but $1200 is now making me want to pick one up
@@BreadandFaxes hey is yours noisy? I picked on up as well but pretty sure FedEx trashed it. Had to be dropped. It plays and sounds good but the amp has so much noise and is super scratchy when turning the knobs. Especially the presence knob. Sweetwater going to send me another one once they get back in stock.
The early Marshall’s were based on the Fender Bassman and not really high gain (even when cranked). It was common to use pedals such as the Dallas Rangemaster to boost the JTM.
If you really want to see how clean the amp can be then stop using your fingers and use a pick. You can get any amp to sound pretty clean using your fingers - but not all of us play that way. This is deceiving.

Great coverage of this little gem from soft to crunchy. I got one and it’s the best amp I’ve owned. Thx J.

What a great player John is
Always love to see your demos. Hope you're doing well, John!
Awesome playing and video. Love the clean sound and i love my ST20C so much more than the Blackstar St James EL34 combo it replaced.
Love the blend of the E906 and whatever room/camera mic is being used. Sounds killer.
Bravo John! Another amp you make me want to buy!
Rock on!
love that 80s synth sound with the amp,awsome change of pace!
Sounds phenomenal. Great playing John
This is an excellent review. Good info and good demo. Thanks.
Glad it was helpful!

I read that the choice of KT66 was a happy accident due to the lack of 5881 supply. I prefer KT66 for sure.
Does the amp have to be modified to accept the kt66?
Nice kind of synthwave beat. This amp is fantastic. I bought it and put it right next to my sv20 s. Awesome? Yesss!

Sounds so good…but he makes everything sound great 😊
wow, John, you coaxed out some amazing tones in the opening track.
Choices & competition in the 20 watt tube combo segment are mind boggling. This model seems a safe & sound proven design.
Great video!!!
Thank you so much for this. Just subscribed
Thanks for the sub!

Excellent playing and tones!
Thank you John!
The video I’ve been waiting for….
Great playing John in that opening. 🍻
Intro jam is awesome!
Amp sounds great. It is something that will last along time. It sounds like a great Rock Amp, but can cover you for all styles.
I put a jensen p12r in mine... Damn, thats great...
These guys are salesmen. They're hear to talk you into buying an amp you probably really dont need if you're not gigging for a living.
I mean on the sales aspect….. duh
But that’s bullshit. A tube amp cranked should be enjoyed by everyone not just a gigging musician.
@@DG-bb1jz aside from reviving the model , from what I can make out they are built in Bletchley England too..under $1000 for the head alone
Duh?
Do you know what a hobby is?

Mark Knopfler .. Marshall player Collector . Great Post on Harmonics
this amp sounds great on you ! :)
I was just about to ask what pedal he is using...then realized thats all amp - really great sound!
Wow, you are an amazing guitar player!
John, PLEASE play along with backing tracks, all we hear are little scratches, that was a very cool tune!!😳 originals, no copyright issue, surf meets bluegrass? 😅 awesome, give us more!
I had a Visual Sounds Dual Tap Delay.... I did a partial trade in for an acoustic guitar. Loved that delay. Miss that delay.....
Great demo, I like 5W
Got to flick the toggle switch on the LP to get that ,,,gack ,gack,gack,gack!!!!
Nice 80s movie backing track you got there, John! 😅
What label is the leather strap in your Les Paul? Imaging look mate. And amazing tone also.
John, what do you mean when you said at the 4:00 minute mark,?
"the differance between the Marshall and the Fender Bassman is, on the marshall the 12ax7 comes first"
A Tweed Bassman had a 12AY7 as the first preamp tube. That tube has less gain. It’s more or less standard to swap it for a 12AX7.
@@drSwan77 right but it didnt make sense out of context like that
It sure is purdy. I want this amp. But where to put it. seriously its a problem at this point.
you can swap out 12AX7 with 12AT7 or 12AU7 for different gains.
good player
I see you using a Petosa Music patch cable. I'd guess someone spent some time in the Northwest. 😉
Hi John. I just got a Marshall JTM Studio Combo based upon your recommendation. The amp sounds great, but anytime I play a C chord (or any C note on the fretboard) I get a weird harmonic vibration. It's more pronounced with humbuckers, but still happens with my Tele. Did you get any kind of vibration from the combo you reviewed? Thanks!
Why would this and the silver jub. have 12s, but the sc and sv combos have 10s?
There is a video explaining why but I can't remember where I ran across it. Something about the 10 sounding as good as the 12 and being able to keep the size of the amp down.
when they put 10's they were really dumb and now they are wiser

With different color magnet caps throughout the 70s . So there was no vintage Creamack model . Vintage Greenbacks and Creambacks were the same speaker.
If its heavy that means that everything that is supposed to be in there is in there
great demo dude if got a 76 twin reverb fender and a 50s fender and several les pauls including my 76 standard tobacco burst and cherry burst 81 custom and 89 ebony standard
Dime everything was the ticket
Who makes the guitar strap on the les paul, first guitar in the video
Great playing - your inner Pete Townshend / P Kossoff
I have it I love mine
Wait is that an LP with a B bender?
yup
Using the drive peadal wirh the amp set clean it sounds really blanketed muffled .
Knobs look cheap, and no location marking.🐐
What are the differences between this amp and the SV20C? Thanks!
A lot of marketing tactics to push sales.
the sv is the 1959 super lead's modern 20 watt version. this is(st 20) the jtm 45 2245 modern 20 watt version. the jtm is cleaner and darker the super lead is punchier and brighter.
@@yaniv-nos-tubes thanks very helpful!
@@josephliptakA Jtm circuit and a Plexi circuit sound completely different.
the sv is a minimized super lead this is a minimized jtm45 with a much better speaker, the sv is more aggressive and harsh this is soft and mellow.
Awesome video! Good lucky for you in youtube journey! I'm stopping my videos today because I am the worst guitarist
Dime this pig, he says ! 😅 love it

I have this amp. So how do you switch to 5w?
the "low" position on the standby switch is 5w the "high" is 20w. just got mine (combo version) today, hooked it to an external cab(1974cx) with a greenback and swapped all the preamp tubes to early 60's mullards, great little amp.
Is it as loud as the sv20?
Instead of saying:"now let's hear les paul a bit" he went the other way 😢😊
Audio is CLIPPED!
these sound good but not at those prices. I'll stick with my Two-Rock CRS
Sounds great, but man it's pricey.
Doesn’t Marshall have enough of my money?
Steve Martin can really play!
He’s a wild and crazy guy!
if you go to gruhns guitar right now you will see my 59 fender strat for sale. beautiful guitar but expensive
2:36:"but definitely its own thing" well, if that's what call swapping power tubes from 6L6 to 5881, then ok ;)
At 3:56 you mention that. You have my respect!
20 watt sounds “ fuller”
Still doesn't justify the $2,000 price tag.
Outside of the classic vibe series I don't know that the price of any gear right now can be justified. Just give it time and they will get ridiculous too. Fender is only gonna listen to people talk about how great they are for the money before they jack up the price. Ala epiphone.

@sjorda12 yeah the plexi head just went down to 999.99 from 1,800.. Now I'm trying real hard to find a way to not justify buying it.
Just got the combo for $1200. Killer sounding amp

overdrive pedal on a Marshall......like bying a Porsche and changing the engine for a Volkswagen diesel.
It’s really not like that at all.
The early Marshall’s were based on the Fender Bassman and not really high gain (even when cranked). It was common to use pedals such as the Dallas Rangemaster to boost the JTM.
No it's more like buying a porche and slapping a turbo on it.
Dime this pig?
All those effects render this review useless. Can we hear the amp?
There is so much disinformation here that I don't know where to begin ...
If you really want to see how clean the amp can be then stop using your fingers and use a pick. You can get any amp to sound pretty clean using your fingers - but not all of us play that way. This is deceiving.
"deceiving"? The fucking hell is wrong with people, man. Calm down.
Let's doing the pros for demos.🤣
Choices & competition in the 20 watt tube combo segment are mind boggling. This model seems a safe & sound proven design.
